We are experiencing problems with our Bosch Worcester Combi - boiler
We are continually having to press the reset button at various time throughout the day, in order to obtain hot water or our heating.

It's clear from the gauge on the system that the pressure is very low ( not even at 1 bar) but we do not have a loop to fill as we have a re-fill tank situated in the eaves on our loft which, I think the boiler draws from automatically when the pressure drops, however I think this is no longer happening and could well be the reason for our troubles.

I have bled all the radiators to ensure no air is trapped and checked everywhere for possible leaks, but everything appears to be fine however the pressure remains under 1 bar.

Bleeding the rads seems to be the national pastime.

You are running the boiler with hardly any water in it. You will damage the boiler if you persist.

You do not say which model

I am in Glasgow and can offer repars/ service.

As your boiler is set up on an open vented sytem then you pressure gauge should read zero it only comes into its own on a sealed system , however if you have a lot of head (height of tank above boiler )above 20 feet you will get say about 1/4 of a bar BUT if the expansion pipe has 90 deg bends, horizontal runs and a restriction the pressure will rise on the gauge instead of the expansion in the tank as you obviously have an overheat fault then i would say you have sediment/debri in the sytem .Check inside your exopansion tank for any sludge in the bottom and what type if its brown rust is present (not good) if its black then a cleaner can be used. the 280 has some verry narow water ways lazer welded into the back panell so cleaning can be a bit of a b....

Strange problem this one. Evidently there is a header tank (in the loft) AND the boiler has in the past registered 1.5 bar. Property is semidetached.

Cannot make sense of boiler being at 1.5bar fed off a header tank.

The feed tank could feed through a non return valve so that expansion takes place as in sealed system , hence higher pressures.[/quote]

Hello Just need to say that a mistake was made with regard to the pressure bar being at 1.5 this is incorrect a fault on our part it has always been below 1 bar. Sorry icon_redface.gif

And has DP visited you in your undefined location from his castle in Glasgow?

Is your boiler all working fine now or are you shivering as the winter sets in?
